- StabilizerWhat is swimming pool water Stabilizer?
- Swimming Pool Liner Swimming pool liners typically refer to vinyl liners, which are installed inside a pre-constructed support structure and are responsible for holding the water inside the swimming pool.
- Sulfuric Acid Reagent Sulfuric acid reagent is a substance often found in pool test kits, and used as a pH-reducing substance in an acid demand test and as an acid indicator in total alkalinity tests.
- Solar Pool Heater Definition Solar pool heaters describe a variety of products, as some pump pool water through tubes heated by the sun, and others serve as mats or blankets that cover the pool water and heat the water as they are exposed to sunlight while insulating the water during evening hours.
- Slow Sand Filter Slow sand filters filter swimming pool water by passing water through sand, where the water trickles through the sand particles, leaving any contaminates behind in the sand.
- Skimmer Plate A skimmer plate is located at the water line, and serves as the location where the surface of the water flows towards the plate, pulling any floating debris into the plate.
- Skimmer Basket The skimmer basket is located just behind the skimmer plate, and collects debris and objects that have traveled along the surface of the water into the skimmer plate.
- Siphon Siphon describes both a process and a device, which often involves using a tube to drain swimming pool water from inside the pool, or a pool cover pump to siphon water from a pool cover.
- Shotcrete Pool Shotcrete pools are constructed by spraying a wet concrete and aggregate mixture onto the swimming pool walls and floors.
- Salt Chlorine Generators Salt chlorine generators manufacture chlorine that can be used by a swimming pool for sanitation, avoiding or reducing the amount of chlorine that needs to be added by other means.
- Sport Pool A sport pool is a design of swimming pool, often built with a constant or near-constant depth, which encourages group and sport activities.
- Sodium Carbonate Sodium carbonate, also called soda ash, is used to increase the level of swimming pool water pH.
- Sodium Bisulfate Sodium bisulfate, or dry acid, is used to lower swimming pool water pH and often will decrease alkalinity somewhat.
- Sodium Bicarbonate Sodium bicarbonate, also called baking soda, is used to increase the total alkalinity of swimming pool water.
- Soda Ash Soda ash, also called sodium carbonate, is a chemical added to swimming pools to increase the pH level of the pool water.
- Shock Treatment Shock treatment, also called shocking or superchlorinating, is the process of adding enough sanitizing agent to a swimming pool to overwhelm any microorganisms in the water, killing or rendering their numbers small enough for safe swimming.
- Saturation Index (SI) The saturation index estimates the point where swimming pool water will no longer hold any more substance, such as minerals or chemicals.
- Sanitizer A sanitizer is a chemical or process designed to destroy or render ineffective harmful microorganisms from reaching levels too high to be considered safe for swimmers in pool water.
- Sand Filter Sand filters are used in the filtration of contaminates and particulate from swimming pool water, with the sand acting as the filter medium.
- Stabilized Chlorine Stabilized chlorine is chlorine normally added to swimming pool water that also contains a stabilizing agent, such as cyanuric acid, designed to slow the destruction of dissolved chlorine in swimming pool water when exposed to UV light (sunlight).
- Sodium Thiosulfate Sodium thiosulfate is a common reagent chemical found in swimming pool test kits, often used to test the pH level of pool water.
- Sodium Sulfite Sodium sulfite is used as a chemical addition to swimming pools to rapidly reduce the chlorine level.
- Sequestering Agent Sequestering agents are chemicals added to swimming pools to bind with metals found in pools, keeping more metal in the water.
- Soft Water Soft water describes water that has a greatly reduced amount of dissolved minerals in the water, creating a corrosive environment in swimming pools.
- Saturation Point The saturation point describes a point in water where the water cannot hold any more of a particular chemical, causing any extra material to remain suspended in the pool water.
- Superchlorinating (shocking) Superclorinating (shocking) a pool is the process of adding shock material into the pool water to meet or exceed chlorine demand, resulting in clearer pool water.
